Got an email from CVS for 50% off posters. Not sure of all their sizes, but the code is "50POSTER". I submitted an order for two 12"x18" today (after some serious photoshopping ) that only cost $6.49 each.

I have split the image into 4 equal parts in case someone wants to print this on 4 pages. I printed each individual piece, cut a few borders, and taped the whole thing with scotch tape. My printer pretty much sucks but here is what it looks like on my wall. .
Here are the 4 pieces if anyone wants to download them.
